I have a Lemon sprout (Aprox 2 months old) that is getting tiny yellow dots on its leaves.
3 days ago I have move them from indoor climate to outdoor climate (Dallas TX). Soil is moisturized. (No direct sunlight). Temperatures around 90F
The affected leaves are the first 4 leaves the it gets when it sprouts.
The leaves of certain plants will have some features not found in all plants. For example, the yellow bumps on the leaves above are specialized glands called nectaries. In this case they occur outside of flowers, so they are also called "extrafloral nectaries. "The bright specks in this lemon leaf are glands filled with citrus oils. The spots are sometimes called "pellucid dots" because they light up when the sun shines through the leaf.
